Question 1:  Based on their answer, prepare a sample floor plan for that specific project (bath, kitchen, deck, addition, full house) and ask the applicant to estimate from it. Time the applicant and confirm accuracy.

Question 2:  

GFCI = Ground fault circuit interrupter
TOW = Top of the wall
AFF = Above finished floor
TTW = To the weather
DATUM = First level, top of finished floor
GWB = Gypsum wallboard
S, = Symbol for a switch that works with one other switch (They both control the same electrical device or devices.)
OC = On center
RO = Rough opening
W1026 = Symbol for steel, wide flange I-beam, 10 inches tall and weighing 6 pounds per foot
NTS = Not to scale

You could also show symbols that indicate cross sections, types of materials by crosshatch, lighting symbols, and the like from a plan and ask the applicant to identify them.

Question 3: 

  • Gluing and nailing acceptable using stainless steel nails (galvanized nails also are acceptable).

  • Outer growth rings facing up 

  • Spacing should be tight because decking will shrink 

  • 2 screws per board at every joist

Question 4:  8-1/4 inches

Question 5:  

Minimum headroom = 6 feet, 8 inches (measured vertically from the top leading edge, or nosing, of the stair treads) 
Nosing overhang requirement = 1 inch, but 1-1/4 inches is recommended. 
Stairway width: 36 inches (minimum for other than a spiral unit)
Step depth = 10 inches (maximum is 8 inches for conventional stairs, 9.5 inches for spiral)
Handrail height = 30 to 36 inches (measured vertically from the top leading edge, or nosing, of the stair treads)

Question 6:  

Spindle spacing maximums = 4 inches from inside to inside 
Guardrail heights = 36 inches 
Height/event that requires stairway or guardrails: stairway with more than 3 steps or 30 inches; deck/landing of 30 inches

Question 7:  Head and side jamb spacing = 1/8 inch; winter = larger spacing larger (will swell in summer); summer = smaller spacing (will shrink in winter)

Question 8: Nail the oak sanitary shoe down into the oak floor at an angle (not into the wall). Cut joints at 45 degrees. Use a 6-penny nail and drill prior to nailing. Nail the flat-stock baseboard, two nails at each stud, with mitered joints that occur at studs. Make sure to miter outside corners and butt-joint inside corners. Use 8-penny nails. Nail decorative upper piece with a 45-degree overlap at different stud, coped at inside corners and mitered at outsides. Use one 6-penny nail per stud at an angle down into baseboard and one into stud.

Question 9:  With a portable circular saw, the plywood should be good side down. With a table saw, the plywood should be good side up.

Question 10:  Standard height for 30-inch tall upper cabinets = 84 inches AFF

Question 11:  This question is somewhat subjective, but the applicant should mention the following items: Level line—shim or cut bottom of base cabinets. Prepare top of upper cabinets for soffit materials and screw them to wall studs end to each other (using clamps). Hold tallers and panels out until counters are installed. The candidate might ask if any special wall treatment about the splash would affect the fit. Add backings for crown and soffit at ceiling for cove and soffit nailing. Attach counters to cabinets and walls. If the applicant mentions hardware and clearance considerations, you might consider higher starting pay.

Question 12:  Standard spacing from counter to bottom of upper cabniets is 18 inches. For conventional outlets, place them every 3 feet.

Question 13:  Place outlets above counters wider than 12 inches. Safety concerns lead this to become code.

Question 14:  Minimum spacing from range to unprotected cabinet above is 30 inches. Minimum spacing for a metal hood is 24 inches.

Question 15:  The blank that has been left for the width of the room should be filled in by the test taker. Grading the drawings is up to the tester.

Question 16:  Grading the drawings is up to the tester.
